The project in five facts.
Challenge, approach and results.
Wastewater containing biodegradable components can be biologically treated with appropriate analysis and environmental control. The main purpose of the diploma thesis is the introduction of operational assessment for small municipal wastewater treatment plants (SMWTP) up to 50 PE in the company JKP LOG, d. o. o. and cost estimation of the newly introduced analyses. The choice of treatment process depends primarily on ** the composition of wastewater,** as we distinguish between municipal and industrial wastewater, which arise in urban settlements or in individual industrial facilities.
Problem
Wastewater containing biodegradable components can be biologically treated with appropriate analysis and environmental control. The main purpose of the diploma thesis is the introduction of operational assessment for small municipal wastewater treatment plants (SMWTP) up to 50 PE in the company JKP LOG, d. o. o. and cost estimation of the newly introduced analyses. The purpose of the diploma thesis is also to review the operation of SMWTP Leše and determine whether it operates in accordance with legislation.
In biological wastewater treatment plants we can remove predominantly suspended, organically degradable substances and nutrients. Which substances and to what extent are removed in a biological wastewater treatment plant depends on various factors, such as: oxidation-reduction (aerobic, anaerobic, anoxic) conditions in the system, wastewater composition (concentration of organic substances, pH, temperature, presence of toxic substances, etc.) and the construction of the treatment plant.
Solution and Method
The choice of treatment process depends primarily on the composition of wastewater, as we distinguish between municipal and industrial wastewater, which arise in urban settlements or in individual industrial facilities. During treatment, a certain amount of waste sludge is produced as a by-product, which requires additional treatment. The composition of municipal wastewater and the amount of waste sludge depends primarily on the way of life in a particular environment (water consumption, garden watering, small industrial facilities, traffic, etc.).
Javno komunalno podjetje LOG, d.o.o. is owned by the municipalities: Ravne na Koroškem, Prevalje, Mežica and Črna na Koroškem. As the operator of the public sewerage system in the municipality of Ravne na Koroškem (Article 6 of the Decree on the Discharge and Treatment of Municipal and Rainwater Wastewater in the Area of the Municipality of Ravne na Koroškem (Official Gazette of the Republic of Slovenia, No.
12/2011, Official Gazette of Municipalities No. 20/2013)) and in the municipality of Prevalje (Article 3 of the Decree on Public Sewerage in the Municipality of Prevalje (Official Gazette of the Republic of Slovenia, No.
28/2002)) they are obliged to provide, within the framework of the public service for the discharge and treatment of municipal and rainwater wastewater, also in a settlement or part thereof that is not equipped with public sewerage, regular emptying of non-flow septic tanks and transport of contents for treatment to the Central Wastewater Treatment Plant (CWTP) Slovenj Gradec or Mežica, collection of sludge from small municipal wastewater treatment plants and its treatment at least once every three years, carrying out initial measurements and operational monitoring or preparation of operational assessment for small municipal wastewater treatment plants up to 50 PE.
